As you wade through the available Kepler cards trying to decide which one to get, EVGA hopes to sway your decision with its new GeForce GTX 680 SC Signature and Singature+ w/ Backplate edition graphics cards. These sleek and sexy looking cards boast higher base and boost clockspeeds, overclocked memory, and 5 Phase PWM board designs with 8-pin + 6-pin power connectors that EVGA claims are optimized for further overclocking.

EVGA GeForce GTX 680 SC Signature

EVGA goosed the base GPU clock to 1084MHz and boost clock to 1150MHz on these cards, up from 1006MHz (base) and 1058MHz (boost) on NVIDIA's reference blueprint, and cranked the the 2GB of GDDR5 memory to 6208MHz (effective), up from 6008MHz on reference cards. As a result, memory bandwidth is increased to 198.66GB/s, compared to 192.2GB/s. The upshot to having higher memory bandwidth is being better equipped to handle large textures and things like anti-aliasing (AA) and anisotropic filtering (AF).

EVGA GeForce GTX 680 SC Signature+ w/ Backplate

EVGA priced the GeForce GTX 680 SC Signature edition at $530 MSRP, or for an extra $20 ($550 MSRP), the Signature+ model comes with a backplate pre-installed for additional cooling prowess. Both cards are backed by a 3-year limited warranty, which can be transferred to subsequent owners via EVGA's recently announced Global Warranty policy.
